She built her career catching killers. This case will cost her everything she believes about herself.
Detective Constance Egan is the sharpest investigator in the St. Louis Metropolitan Police Department's Homicide unit - a woman whose uncanny ability to read crime scenes and decode human behavior has made her both indispensable and unsettling to everyone around her. When a woman's body is found on a levee south of the Chain of Rocks Canal, arranged with disturbing precision, Constance recognizes something in the ligature pattern that she can't explain. Something older than her badge. Something lodged in a memory she didn't know she had.
